<DIV><FONT face=Arial size=2>hi guys:</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>we are having Q.921 DLPI problem when trying to
establish ISDN layer 2 connection with the E1 switch of the telecom carrier, the
carrier switch is unable to establish layer 2 link with our * server with a
quad E1 card, </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Here is a trace provided by telecom.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>

N DL_RELEASE_IND <BR><BR>U <－
N (PRA_PROTOCOL_CONFIG) <BR><BR>U <－
N DL_ESTABLISH_REQ </FONT><BR></FONT></DIV>
<DIV><FONT face=Arial size=2>look like this <FONT face="Courier New"
size=3>DL_RELEASE_IND is part of Q.921, but i don't see this in libPRI, is the
LIBPRI implementation missing the DLPI part of the Q.921? I also found some
free code of Q.921 Q931 on the net, Linux and FreeBSD seams also contains this
DLPI in their isdn drivers.</FONT></FONT></DIV>
<DIV><FONT face="Courier New"></FONT> </DIV>
<DIV><FONT face="Courier New">reading the libpri code, it tells it is doing the
ua only, no DLPI, shall we add DLPI or we can tell teleco to only use ua layer 2
link establishment?</FONT></DIV>
